a meaningless but emphatic expression used in the end of a sentence or a phrase to mark a joke or an obvious fail. Endaznie is usually pronounced louder and emphatic in the end of a sentence that makes no sense. It is commonly used in the language of the people of Belene in Bulgaria. Most of the world outside Bulgaria doesn't even suspect of this strong expression.
- Guess what I had for breakfast today?
- Which school did you go to?
